Selective sPlenic flExure Mobilization for Low colorEctal Anastomosis After D3 lYmph Node Dissection (Speedy Trial)

In the Low Anterior Resection of rectum for cancer, the section level of IMA and the need of SFM is still debated.
The aim of this study is to explore the different impacts of high and low ligation with peeling off vascular sheath of inferior mesenteric artery (IMA) in low anterior resection of the rectum for cancer. This study purpose to demonstrate that low IMA ligation, sparing of left colic artery (LCA) and selective SFM results in higher anastomotic leakage rate than high IMA ligation with routine SFM (with the difference of more than 5%).
